Molex MX123 Sealed Connectors

Molex MX123 Sealed Connection System is a fully sealed, high-performance system, designed for transportation power-train applications that require reliable connections in high-vibration under-the-hood environments. The MX123 sealed connection system from Molex meets GMW3191 specifications, ensuring this product can perform in very harsh, hot, high-vibration environments. This system utilizes matte-seal technology, creating an extremely resilient sealed connector system with a small package. Features include multiple polarization, wire-dress and PCB-tail options, and integrated TPA and CPA components, assisting in keeping the interface mated while freeing up valuable time in the assembly process.
